It is typically advantageous to insulate abrasive wheels from atmospheric agents, for example by enclosing the abrasive wheels in a package (e.g., a plastic package).
[043] Now referring to Figures 1, 2A-B, 3A-D and 4A-D, in some embodiments, a package for abrasive wheels is provided. The package includes a base 11 and a cover 12 configured to couple to the base 11. The base 11 provides an inner space between a side surface 11a, an open end lib having a diameter Dopou and a closing plane end 11 c having a diameter DGIosed. The inner space of the base 11 is adapted to contain stacked abrasive wheels having a diameter Dwheel. The side surface ha has a projecting portion lid that projects from the closing plane end 11c and that has a diameter Dproi. The cover 12 is configured to couple to the base 11 at the open end llb to close the inner space. The base 11 and the cover 12 insulate the abrasive wheels from atmospheric agents when the base 11 and the cover 12 are coupled. The cover 12 includes a projection 12a that is shaped to define an annular plane portion 12b. The annular plane portion 12b has an inner diameter Diu and an outer diameter Dout. As will be described herein, some of the elements of the base 11 and cover 12 can be sized and shaped to complement each other. For example, the shape of the base 11 and/or cover 12 and/or the various diameters can be selected to better accommodate the abrasive wheels within the package 10, to promote a more convenient stacking of multiple packages 10 on top of one another and/or to promote a more convenient stacking of multiple bases 11 and/or covers 12 on top of one another.
[044] The base 11 and the cover 12 can be made of any type of material that insulates the abrasive wheels from atmospheric agents. Preferably, the base 11 and the cover 12 are made of plastic material.
[045] In some embodiments, the diameters described herein have the following relative relationships: Dvvheel Din < Dproj Dclosed < Dopen Dout.
[046] The annular plane portion 12b corresponds to an annular plane space at the periphery of the cover 12. The inner diameter of the annular plane portion 12b is defined by joining the outer most portions of projection 12a together by a hypothetical circular joining line, and the outer diameter of the annular plane portion 12b is the outermost diameter of the cover 12.
The inner diameter of the annular plane portion 12b is preferably selected to be equal to or greater than the diameter of the abrasive wheels to be stored in the package 10, that is Dwheel D. Similarly, the outer diameter of the annular plane portion 12b is preferably greater than the diameter of the abrasive wheels and the inner diameter, that is Dwheel Din < Dt In some embodiments, the inner diameter of the annular plane portion 12b is substantially equal to the diameter of the abrasive wheels, that is Din = Dwheel. In other embodiments, the inner diameter of the annular plane portion 12b is strictly greater than the diameter of the abrasive wheels, that is Dwheel < Din.
The inner diameter of the annular plane portion 12b is preferably selected to be equal to or greater than the diameter of the abrasive wheels to be stored in the package 10, that is Dwheel D. Similarly, the outer diameter of the annular plane portion 12b is preferably greater than the diameter of the abrasive wheels and the inner diameter, that is Dwheel Din < Dt In some embodiments, the inner diameter of the annular plane portion 12b is substantially equal to the diameter of the abrasive wheels, that is Din = Dwheel. In other embodiments, the inner diameter of the annular plane portion 12b is strictly greater than the diameter of the abrasive wheels, that is Dwheel < Din.
[047] In the embodiment shown in the Figures, the projection 12a is a pseudo-circular projection wherein a circle of diameter Din is provided with three (3) recesses 12c. It should however be understood that the shape and number of recesses 12c can vary, or that the recesses 12c can be absent.
[048] In some embodiments, the base 11 is provided with a side surface 11a, an open end llb having a diameter Doper, and a closing plane end 11c having a diameter Debsed. The side surface 11a is also provided with a projecting portion lid having a diameter Dproj and that projects downwards from the closing plane end 11c. The diameters are preferably selected such that DI.; Dclosed< Doper,. In some embodiments, Dpipi is substantially equal to Dclosed, that is Dproj = Dclosed. In other embodiments, Dproj is strictly smaller than Dclosed, that is Dproj < Dclosed.
[049] In some embodiments, the diameter Dproj of the projecting portion lid is selected such that Din < Dproj D.ut. Preferably, the diameter Dproj of the projecting portion lid is further selected such that when the projecting portion lid is resting on the annular plane portion 12b of a cover 12 and abutted against a side surface of the projection 12a of the cover 12 on one side, the entirety of the projecting portion lid stays within the annular plane portion 12b, without extending outside the surface defined by the annular plane portion 12b.
[050] In the embodiments shown, the projecting portion lid is circular and continuous, and is provided at the periphery and under the closing plane end 11c. However, it should be understood that the projecting portion lid can be discontinuous or provided with recesses or notches or have other shapes.
[051] In some embodiments, the projection 12a has a height that is equal to or smaller than the height of the projecting portion 11d, such that the projecting portion lid is allowed to rest upon the surface defined by the annular plane portion 12b when the base 11 is stacked upon a cover 12.
[052] The projecting portion lid of a first package 10 can be provided on top of the cover 12 of a second package 10, such that the projecting portion lid of the first package rests on the surface defined by the annular plane portion 12b of the second package.
Preferably, the diameter of the projecting portion lid is slightly larger than the inner diameter of the annular plane portion 12b such that the first package fits onto the surface defined by the annular plane portion 12b and allows stacking of the second package onto the first package.
Preferably, the diameter of the projecting portion lid is slightly larger than the inner diameter of the annular plane portion 12b such that the first package fits onto the surface defined by the annular plane portion 12b and allows stacking of the second package onto the first package.
[053] In some embodiments, the diameter of the open end lib is equal to or smaller than the outer diameter of the annular plane portion 12b, that is Dopen Dõt. In some scenarios, Dopen = Dout= In other scenarios, Doper, < Dout.
[054] In some embodiments, the side surface 11a includes a base portion lie, an annular base belt portion llf and an edge portion 11g. The base portion 11e extends from the closing plane end 11c to a first end of the annular base belt portion llf, and the edge portion 11 g extends from a second end of the annular base belt portion llf to the open end lib. In some embodiments, the annular belt portion llf protrudes away from the side surface and defines a shoulder 11h between an outer surface of the annular base belt portion llf and the edge portion 11g.
[055] In some embodiments, and as shown in the Figures, the base portion lie has a frustoconical shape having a first diameter Dclosed at the closing plane end of the base 11, and a second diameter Dbeit at the first end of the annular base belt portion llf.
It should be understood that the second diameter Dbeit is measured on the base portion lie, and at the edge between the base portion lie and the base belt portion llf. In other words, the second diameter Dbeit does not represent the protrusion of the annular base belt portion 11f, but rather the largest diameter of the base portion lie. Preferably, the first diameter Deiosed is smaller than the second diameter Obeli, that is Dbioõd < Dbeit. In other words, the frustoconical base portion lie is angled such that the smaller diameter is closest to the closing plane end 11 c and the largest diameter is closest to the annular belt portion llf.
It should be understood that the second diameter Dbeit is measured on the base portion lie, and at the edge between the base portion lie and the base belt portion llf. In other words, the second diameter Dbeit does not represent the protrusion of the annular base belt portion 11f, but rather the largest diameter of the base portion lie. Preferably, the first diameter Deiosed is smaller than the second diameter Obeli, that is Dbioõd < Dbeit. In other words, the frustoconical base portion lie is angled such that the smaller diameter is closest to the closing plane end 11 c and the largest diameter is closest to the annular belt portion llf.
[056] In some embodiments, the edge portion 11g has a cylindrical or frustoconical shape.
The edge portion 11g has a first diameter Dbelt at the second end of the annular base belt portion 11f and a second diameter Dopen at the open end llb of the base 11.
Preferably, the first diameter Dbelt is equal to or larger than the second diameter Dopen, that is Dbelt Dopen.
More specifically, when the edge portion 11g has a cylindrical shape, Dbelt =
Dope.. Similarly, when the edge portion 11g has a frustoconical shape, Dbelt > Dopen.
The edge portion 11g has a first diameter Dbelt at the second end of the annular base belt portion 11f and a second diameter Dopen at the open end llb of the base 11.
Preferably, the first diameter Dbelt is equal to or larger than the second diameter Dopen, that is Dbelt Dopen.
More specifically, when the edge portion 11g has a cylindrical shape, Dbelt =
Dope.. Similarly, when the edge portion 11g has a frustoconical shape, Dbelt > Dopen.
[057] Now referring to Figure 5, an embodiment of the base 11 is shown where more pronounced half-cone angles a and p of the base portion 11e and the edge portion 11g, respectively, are shown, for illustrative purposes. In the embodiment shown at Figure 5 as well as in the embodiment shown at Figures 1, 2A-B, 3A-D and 4A-D, the half-cone angle a of the base portion 11e and the half-cone angle p of the edge portion 11g are of opposite directions. In other words, the base portion 11e is angled outwardly from the bottom up of the base 11 while the edge portion 11g is angled inwardly from the bottom up of the base 11.
Preferably, the half-cone angles a and p are selected such that a -6., or more preferably such that a > -p.
Preferably, the half-cone angles a and p are selected such that a -6., or more preferably such that a > -p.
[058] In some embodiments, the half-cone angle a is selected between about 0.5 and about 4 or between about 0.5 and about 4.0 , and preferably between about 1 and about 3 or between about 1.0' and about 3.0'. By selecting a base 11 having a frustoconical base portion 11e with a half-cone angle a between about 0.5 and about 4 , several bases 11 can be nested into one another when no abrasive wheels are stored therein. This can for example allow saving space when shipping packages 10 to a location where the bases 11 will get filled with abrasive wheels. In some embodiments, the half-cone angle p is selected between about -0.2 and about -1.1 , or between about -0.25 and about -1.0 . In some embodiments, a> -p, wherein the half-cone angle a is between about 1.0 and about 3.0 , and the half-cone angle 6 is between about -0.25 and about -1.0 .
[059] Now referring back to Figures 1, 2A-B, 3A-D and 4A-D, the cover 12 can also have an annular cover belt portion 12f that protrudes away from the side surface of the cover 12.
The annular cover belt portion 12f is preferably shaped to correspond to the annular base belt portion 11f and can fit onto the shoulder 11h when the package 10 is closed.
